I have created a C.C.I book and here is a small sample of the problems. In the December section, there are 16 problems and each problem has 2 options. One was created for 1st grade and one was created for 2nd grade. I also include one with blanks to allow you to customize the difficulty of the problem and adjust for individual students.
